In fact, in view of [EMAIL PROTECTED] boxopen doesn't make sense, so yet
simpler:
join08=: [EMAIL PROTECTED] }. <@[ ;@,. ]
To Raul: join02 works fine. In fact its latter part is used here.
Version 08 now replaces Phrases/Strings in Wiki. For the record,
it was essentially:
join09=: [EMAIL PROTECTED] ;@}.@,@,. ]
20 ts 'a join09 c'
